1 A further object of my invention is to provide a wrench that will function as a pipe turning means, and also as pincers.

A still further object of my invention is to provide a wire cutting means actuated by the jaw pinching means.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawings forming a part of this specification, in which like characters will apply to like parts throughout the different views.

Referring to the drawings: I

Fig. 1 is a side view of the wrench, partly in section.

Fig. 2 is a transverse view'of Fig. 1.

Fig. 3 is a modification of. the wrench handles.

Fig. 4 is an enlarged fragmentary detail, showing the variable pivot points.

'The mechanism herein disclosed consists of a handle 1 having a laterally extending jaw 2 integrally connected to the end thereof. The said handle has'a corrugated slot 3 as shown in Fig.4, the said slot functioning as hereinafter described. Slidably positioned on the handle is a jaw 4, having a web 5 integrallyconnected and adapted to engage along the edge of the handle 1. Rear wardly positioned in the web is a pin 6 transversely extending from both sides thereof for the purpose later described.

The jaw 4 is provided with an eye as indicated by dotted lines 7, and in which the handle 1 slidably engages. Pivotally attached to the handle is an adjustingleverS, the said leverbeing U-shaped to engage over the handle as shown at A in Fig. 1, and being tensioned by a spring 8 shown by dotted lines in Fig. 3. The pivoting means consists of a pin 9 having a central portion flattened, the sides of which are parallel to each other as shown at B in Fig. 4, the said flat portions being transversely positioned to the lever.

It will be understood that the Said" a.. is

adapted to extend through the-slot '3 and engage rigidly in both sides of'the lever; and being so arranged, it is possible to move the said lever longitudin'ally from one end of the slot to the other when the lever is rocked'transversely to the handle as shown by dotted lines C; and when rocked to such position thepingwill engage-in the slot as shown by dotted lines D in Fig. 4 for the purpose of passing between the points E to a selected seat or trunnion point, opening the jaws of the wrench as desired. When being thus seated, the lever is free to rock to parallel alignment with the handle andfstation:

arily supported, but free to rock when the wrench is used as pliers or as a pipe wrench.

Then the lever is being rocked to its transverse position, the noses 10 engage with both ends of pin 6 as retracting means for jaw 4,

as shown by dotted lines in Fig. 1, and by this engagement the jaw is carried by the lever to the selected distance. As the lever is rocked rearward, the said jaw is driven forward by the arcuate portion F adjacent the nose,"

which functions as a cam engaging on the back of aw 4 as at G; and llkewise the arouate portions 11 for retractlon, engaging with both ends of the pin. In 'Figs. 1 and 3 the said jaws are toothed as at '12, although smooth jaws may be provided.

As a convenient means for clipping wire, I have provided an aperture '13 in the handle 1, which is spaced ashort distancefrom the jaw member 2, and to co-operate therewith a cutting edge 4 is provided on one'side of jaw 4, and as a means to prevent contact of the j aw-member on the opposite side I have removed or provided a curvature, as shown at 14 in Fig. 1..

In Fig. 3 is shown amodification of the lever, which is curved outward from the handle and is the preferred form when the wrench-is used as pliers,'wire cutters, or pipe wrench. The drawings also show'the jaws positioned at an angle relative'to the handle the angle may be varied, or the jaws may be positionedat right angles to the handle, any

of which modifications will not interfere employed as lie within the scope of the apfeatures; Such other modifications may be pended claim. I 7

Having fully described 111 I claim and desire to s'ecurel 1s: 1 Y

' A wrench of the kind described, comprising a handle having a slotlongitudinally positioned therewith and curvatures along both sides of theslot oppositely disposed to invention, what each other as seating means forpivotal en 'gagement, a lever having a pin with a central portion flattened and parallel to each other,

functioning as a trunnion on which the lever is rocked, a jaw laterally extending and integrally connected to the handle, a second 1 jaw having an eye to slidably engage'on the handle, said jaw having a Web laterally extending and adaptedto bear on the edge of the handle as a bracing means for its respective jaw, a pin extending through the end of the web as means by which the said jaw is retractedby rocking the lever.

In testimony whereof I afiix my signature.
